@ UMZZ Joniv H. ownns, or BACINE,,WISGO1\TIN.

To allwhom itimag concern: 1 Be it known that'l, JOHN H. ()wnNs, acltlzen of the :United States, andresident of Racine, in the county ofRacine and'State of \Visconsin, have invented certain new and usefulImprovements in-Traps or Clean-Out Covers; and I do hereby declare thatthe following is-a full, clear, and exact description .thereof. e

My invention refers to cap closures for plumbers traps or clean-outcovers, which are particularly adapted to be sunk into the floors ofbathrooms or the like, the caps being in threaded union with the mouthof the trap whereby they can be removed for various purposes.

In caps for traps of this general type the usual method of removing themis to provide such traps with project-ions, and these projections are aconstant annoyance as they preclude the desirability of obtaininga'flush floor and thus frequently cause individuals to stumble over theprojections.

Other types of caps attempt to overcome this objectionable feature byusing countersunk recesses. These recesses are formed so as to avoidprojections above the floor,'but

in this type of cap there is a liability of individuals catching theheel of their shoe or other part of the foot into the recess, andfurthermore such recesses form dirt traps. Hence they do not overcomeall of the objectionable features of the projecting head, nor do theymeet the demand for the flush drop coveror cap. V

My invention has for its object to provide and efiective flush cap timeprovision is had for removing such flush cap closure. The arrangementand construction of my inventlon, essentially embod es a polygonalrecess in the upper face of the cap,

and a complementary shaped plate. adapted to fitwithin the recess topresent a smooth uninterrupted surface. Under normal conditions theplate is also provided upon its under surface with a projecting head forthe reception ofa suitable tool. Thus when it is desired to remove thecap,,the plate is 11fted from the recess and reinserted therein, withits head side projecting upwardly so as to provide means for receivingthe tool, whereby the cover can be readily unscrewed from the body ofthe trap. I

With the above objects in view, the invention consists in certainpeculiarities of con- T t-Ar on cnnaugou'r covert.

struction, combination andarrangement of parts as. are hereinafter setforth with ref-1 erence .to .the'accompanylng drawlng and subsequentclaim.

-. Int-he drawing:

'Figure 1 represents a plan-view of'a cap embodying the features of myinvention,- the 0 same being illustrated with-a square plate features.

Figure 2 represents across-section of the cap fitted tothe mouth of atrap of any desired type, the complementary,shapedplate for the coverbeing shown in its normal position with the head thereof extendingdownwardly, whereby a flush upper surface is" formed, thesection beingindicated by line 22}of Figure 1, and

Figure 3 is a similar sectional view of thedevice, showing the removableplate reversed and fitted into the squared recess preparatory to the capbeing removed. In this position, the cap closureis to all intent andpurpose, taken in connection with the re- 1 movable plate similar to thestandard cap in appearance.

Referring represents a cap closure having an annular threaded flange2,-which flange is adapted to by character to the drawings 1 l enter thethreaded mouth of a trap body 3,

as best shown in Figure 2.

The central portion. of the upper surface of the cap,fis provided with arecess l, the

same being formed with rectangular side walls 5, and the centralport-ion of this re-. cess is countersunk to form a pocket 6. The

pocket, in this instance, is shown with recsaid pocket is adapted to fitsnugly against the sideedges of there cessfi to thus form anuninterrupted surface, when'the upper face 9 of the plate is exposed.Hence it will be seen that the plug plate is provided with a smoothface,and from its opposite face there is extended a squared i I.

'7, which'is provided for the purpose 1 Y head of receiving atool,.whereby the cap closure can be removed when desired.

As shown in Figure 3 of the drawing,the plate 8'has been reversed withrelation plug:L to t e cap'rec'ess- 4, whereby the head 7 extends abovethe floor for the purpose of receiving the tool, and in Figure 2 of thedraw ing, the plate is shown in its normal condition, in Which it formsin connection with the adjacent surface of the cap, an uninterruptedface, whereby the recess in said cap is closed and there is no liabilityof an accident, due, to an individual coming in contact With theprojection. As shown in Figure l in this instance I have provided aslight indenture 5 in one of the Walls 5 of the rec tangular shapedrecess, for the purpose of inserting a blade or other instrument,whereby the loosely fitted plug plate can be readily lifted out of itsseat.

While I have shoWn and described the cap recess as being square and innested-engagement with a correspondingly squared plate, obviously theshape of the recess may be varied Without departing from the spirit ofthe invention, as for example it may be six or eight sided. It is alsointended that the screw threaded cap closure may be used in connectionWith any type of floor traps.

I claim:

Acap closure of the type described, having a polygonal shaped centralrecess in its face, thesarne being formed with a head receiving pocketand a complementary plug plate adapted to be loosely fitted Within thecentral recess, the plate having one uninterrupted smooth side and atool receiving head extending from its opposite side, the head beingadapted to. rest Within the recess pocket When thesmoothside of theplate is uppermost to thus form an uninterrupted cap surface.

in testimony that I claim the foregoing l have hereunto set my handatrRacine,1in 'tl1e county of Raclne and State of Wisconsin.
